The growth of the oil industry has created an increase in the movement of heavy materials and equipment into remote parts of central and south Texas. The state’s maintenance forces were not able to keep up with the associated road repairs, so the Texas Department of Transportation (TxDOT) developed a prioritized list of projects in need of repair or reconstruction. The list contained 28 projects worth a total of $183 million and three additional projects that would be included if budget allowed. The design was completed by TxDOT consultants and was completed prior to the proposal. The joint venture of Austin Bridge and Road and Angel Brothers, selected our team as the lead designer as they pursued and delivered these projects through a design-build approach. The team developed a strategy to execute all 31 projects, which totaled 274 miles over a 13,000 square mile area.
Key success factors included:
Geographic-based strategy to supply labor and resources.
Logistics and planning for working remotely over a large area
Communications to promptly respond to material needs
Alternative pavements to reduce project budget
RFIs and design revisions addressed promptly in the field
ProjectWise site to provide remote access to design revisions
Traffic report to track number of vehicles, axles and weight on completed projects to support warranty requirements
Although TxDOT had completed the design for the 31 projects, we provided alternative technical concepts (ATC) that reduced cost and schedule, including pavement design, typical sections and maintenance of traffic. For example, the team proposed closures and detours of larger more remote sections to provide a consistent flow of materials to the site without starts and stops. As a result, many of the projects were completed under TxDOT’s original budget, which allowed funds to be used on the three optional projects.
